Our new HP Oficejet Pro L7780 can send faxes but can't receive

We are on wireless for our printer. The HP L7780 is connected to power, phone cord (using our extra long phone connector as theirs was WAY too short), and a router to print wirelessly. We are a small business office and I can't seem to find any help, manual, directions. I need help!!! Help us receive those faxes. You are the Master

Our fax line is the second line in the hunt so there is a line share device on the line (The Stick). Our phone vendor tried a different line share device but still had the same problems. (1) The fax takes forever (4-6 rings) to pick up even though it's set to 2 rings, (2) when it does work, which is rarely, we might get 1 or 2 faxes then can't receive anything. The sender hears ringing but is eventually disconnected. Both our service provider and phone vendor have been here trying to resolve the issue. If the vendor technician plugs in his test set it does ring when his office sends a test fax. However, if he then plugs the fax in, nothing happens.

I too have a problem with HP7280. I can send faxes but not receive. I am using Cox digital cable phone service and have one phone line for phone and fax with distinctive ring for faxes. HP technical support tried test fax and he himself heard the distinctive rings. He basically ended call saying sorry but HP has problem with incoming digital phone fax signals and he had no solution.

Any ideas for solution with this model? Or do you know of any all in one combos, perhaps another brand that will work with digital signal?

First things first, i really want to know how things being setup in your end. Let say for example, from the walljack what is the device connected to it. Or if your using one line for both incoming calls and faxes. Or if your using a DSL also for that same phone number for faxing/incoming calls.

Those are just severa factors that affect your problems. Meanwhile, i cant give you a solution on your issue since i still dont have a clear picture on are the devices connected with each other. ALso, its really advisable that you need to use the telephone cord that came out with the box.

This is strange. Sounds like noise is in the line. Try searching the line for bad spots or replace the line. The ends could have corrosion on them also. The wires are most likely copper and the corrosion will be green. Check the box on the side of your house also. I would have the phone company check for noise in the line for you. Good luck.

pleass make a copy from the printer
either you use a dedicated line for phone and fax or the same line for phone and fax
then perform a power drain on the printer
steps to perform a power drain
press and hold the power button down
holding down the button
unplug the power cable from the rear access of the printer
hold down the button for 10 secs
then first replug the power cord
then reboot the printer
press the setup icon(it resembles a wrench) on the printer touch screen
then go to tools
then select run fax test
then you can come to know what is the problem
if there is dial tone failure you need to check the phone line
if all says pass
then go to setup once again
then go to advanced fax setup
then check fax speed
if it is fast set it to medium
then check the ecm(error correction mode)
set it to off from on
then go to automatic reduction
then set it to off
then go to basic fax setup
then check the rings to answer
please make sure that the rings to answer for fax should always be 2 rings more than the telephonic answering machine
run a fax test again
then try sending a fax to the number(1-888-473-2963)

you will get a return fax
if the fax test says that the fax hardware failed please contact the hp tech support

1. Press the Setup button - Press OK2. Scroll to Tools - Press OK3. Press OK on Run Fax Test4. It will list you possible causes why you are not able to send/receive fax

If you cannot solve the issue with the Fax Report, you can do a semi-full reset on printer( do not do the semifull reset on printer if connected to wireless, If you do so, the printer will loose wireless connectivity to router and you will have to setup the printer on router again )

Disconnect the power cord from back of printer ( when printer is powered on )Hold the # and 6 button and while holding connect the cord back

This reset will Erase fax logs, wireless connectivity any other memory stored in printer

Follow the instructions on printer screen to re-align the printer and cartridges

Try to send/receive fax and it should work.
